Abstract: A signal level detection device 1 and a signal level detection method according to a means for solving a problem of the present invention varies a cut-off frequency ?c, of a variable low-pass filter 3 which filters a signal level r. The cut-off frequency ?c is varied based on the signal level r or information referred to for estimating the signal level. The signal level detection device 1 and the signal level detection method therefore reduce a delay of a rise of the obtained signal level r from an actual signal level, and sufficiently remove noise superimposed on the signal level r even when the signal level r is extremely low. Accordingly, control performance improves regardless of a degree of the signal level r.
